HexCmp

HexCmp is a HEX editor that allows you to compare the contents of binary files. Files are compared on the fly and files of up to 4 gigabytes are supported. The program can highlight the differences, synchronize scrolling of viewed files and display information about them in an info panel in several data formats. In addition to a full comparison of files, users of HexCmp have the ability to compare their individual fragments - you can view the differing blocks and customize their color display. Comparison of not only binary but also text files is supported. You can search for hex and text strings, undo and redo actions, as well as use standard editing functions in HEX mode. HexCmp is shareware with a 15-day trial, its interface is available in 12 languages, and it can be fully operated from the keyboard.

HexCmp allows users to efficiently compare binary and text files, highlighting differences and supporting files up to 4GB.
